HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 433,755, dated August5, 1890.

Application led Apn'l 25, 1889. Serial No. 308,588. (No model.)

.To all whom t may concern.:

Be itknown that I, JOHN H. VILLIAMS, a citizen of the United States ofAmerica, residing at Maple IIill, in the county of IVabaunsee and Stateof Kansas, have invented certain new and useful Improvements in Hay-Presses; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specication.

My invention relates to certain new and useful improvements inhay-presses, and is designed more especially as an improvement upon thepress set forth in my patent dated April 26, 1887, No. 361,912; and mypresent invention consists in the construction and combination of theparts, as will be hereinafter fully set forth and particularly claimed,whereby I am enabled to dispense with certain parts employed with mysaid patented press, thereby simplifying the same and making a -cheaperpress.

In carrying out Inyinvention I employ two crank-shafts, upon which aremounted cogwheels which mesh with each other, one of said shaftscarrying a beveled pinion which meshes with a smaller pinion having aspringactuated clutch member, said pinion and clutch being carried bythe driving-shaft. The crank-arms are connected by pivoted links to thetoggle-levers which operate the follower so that said arms and linkswill, as hereinafter described, be turned to move the follower into thebaling-chamber, and when said arms pass beyond their dead-centers thebale reacts to exert a rebound of the follower to more rapidly continuethe movement of the cranks, and hence cause the clutch member to revolvefaster than it was originally rotated by the shaft, such more rapidInovement of the clutch-member permitting the quick retraction of thefollower without the necessity for changing or increasing the rotationof the main shaft.

My invention further consists in providing the baling-box at the mouththereof with a pivoted cross-bar operated by the follower to keep theopening free when the follower enters the baling-box. The baling-box isalso provided with a hinged bottom board which can be raised and loweredfor increasing and diminishing the size of the baling-box.

In the accompanying drawings, Figure lis a plan view of a hay-pressconstructed in accordance with myinvention. Fig. 2 is a longitudinalsectional view of the same. Fig. 3 is a transverse sectional view takenthrough the line a: x of Fig. l. Fig. et is a sectional view takenthrough the line y y of Fig. 1. Fig. 5 is a detail plan viewAillustrating the relative position of the parts when the plunger beginsits return movement.

My improved baling-press is adapted to be operated in a horizontalposition, and the frame thereof consists of four longitudinalcorner-beams A A, connected by suitable cross-beams, and at one end ofthe press are mounted beams a a, which are provided with bearings forone end of the toggle-levers B' B, the opposite ends thereof beingconnected to the follower, and these toggle-levers are operated bycrank-arms, the construction and operation of which will be hereinafterSet forth.

One end of the press is provided with beams A', which are provided neartheir centers with cross-pieces a', upon which are journaled shafts Cand C', each of which. is provided with a crank-arm c c', the ends ofwhich are connected to links D D, which connect with the toggle-levers,the said levers being pivotally connected to the follower and one end ofthe frame of the press, as aforesaid. Each of the shafts C and C hasrigidly keyed thereon a cog-wheel to cause the shafts to move in unisonwhen turned by the beveled wheel F, mounted on the shaft C', andoperated by a pinion f, mounted on the driving-shaft. The pinion f isloosely mounted upon the drivingshaft G, and has its clutch memberengaged by a spring-actuated clutch member g, which slides upon a spline0c, formed with the driving-shaft.

The bearings b and h at each side of the press are substantially on aline with each other, and the bearings attached to the follower aresecured to diagonally-oppo site corners thereof to equalize the pressurethereon.

The operation of myinvention in so far as described is as follows: Whenthe driving- IOO shaft G is operated, the shafts C C will be turned torotate the crank-arms mounted thereon, which by means of the links D Doperate the toggle-levers to move the follower inward in the baling-box.By providing the driving-shaft with a clutch when the follower hasreached the limit of its movement the .links and cranks will have passedtheir deadcenters, and the resilience of the hay will cause thetoggle-levers to spread rapidly, thus continuing the revolution of thecrank-arms and the pinion f more rapidly than before, so that the clutchmember of the pinion f will move faster than the determined rotation ofthe main shaft, the yielding clutch member permitting this, and theresult being that the follower is retracted without necessitating a change of speed of the main driving-shaft. As soon as the follower ceasesto act upon the 2o 'clutch member the driving-shaft again acts to repeatthe pressing operation.

To the frame of the baling-box are pivoted I arms H H, which areconnected to each other by a cross-piece h, the under side of these armsbeing curved, as shown, and with said curved portion engages a cross-barfi, attached to or carried by the follower, the said crossbar i movingin slots provided for the same. Upon the rearward movement of thefollower the cross-bar fr', attached thereto, will engage with the endsof the arms H to depress the cross-piece h, thus feeding projectingportions of the charge of hay or straw into the balingboX. Thiscross-piece, lying below the upper surface of the baling-boX, willpartially cut off the feed-opening, and when the follower is forced intothe baling-box the cross-piece 7L will be raised to give an unobstructedand clear passage-way for the follower, which will be free from strawliable to catch between the upper edge of the follower and the end ofthe baling-boX.

The lower floor of the balingbox has a hinged bottom J, supported at theend of the press by a cross-piece 7c, through the ends of which passrods L, the upper ends of which are screw-threaded so that thehand-wheels m may engage therewith. When the handwheels are turned inthe proper direction, the hinged board may be' lowered to increase thesize of the baling-box sufficiently to permit the easy removal of thebale therefrom.

' I claim* 1. The combination, in a baling-press, of a driving-shaft G,journaled in suitable bearings and provided with a pinion f, having onemember of a clutch, the other member being movable therein and having aspline engagement therewith, and a spring thereon bearing against saidmovable member, two vertical crank-shafts geared together, and abevel-wheel F, keyed on one of said shafts and driven by the pinion,toggle-levers B B, connected by links D D to the cranks and having theirends connected, respectively to a fixed portion of the press and to thefollower, substantially as set forth.

2. The combination, in a continuous balingpress, constructedsubstantially as shown, of a follower provided with bearing-blocks b',toggledevers B B, pivoted to said bearingblocks at one end and at theiropposite ends to bearing-blocks secured to the end of the frame,cross-pieces a', independent crankshaft-s journaled therein and eachconnected to said toggle-levers by links D D, intermeshing cog-wheelscarried by said crank-shafts, a bevel gear-wheel F, mounted on one ofsaid crank shafts, a drivingshaft G, a clutchsleeve engaging a spline onsaid drivingshaft, a pinion f, engaging said bevel-wheel F and having atoothed hub, and a spring for holding the clutch member in engagementwith the toothed hub of the pinion, substantially as set forth.

3. The combination, in a continuously-op erated baling-press, of thecrank-shafts geared together, as described, a follower, toggle-1eversand links connecting the latter with the crank-shafts, a driving-shafthaving movable and stationary clutch members, a pinion carried by one ofthe latter to actuate the crank shafts, together with a baling-boX, acrosspiece/r' on the follower, pivoted arms H H, curved on their underfaces, and a cross-bar h, connecting said arms H H, whereby the reboundof the follower under the action of the compressed hay will revolve oneof the clutch members faster than it was rotated by the driving-shaftand simultaneously move the arms H H to operate the cross-bar h,substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
